Negative slack indicates timing failure. Resolve this by pipelining your RTL, simplifying complex combinational paths, or evaluating if your target clock frequency is realistic for the chosen process node. synopsys design compiler tutorial 2021
Missing else or default statements in combinatorial always blocks.
To run this automated script from your linux command line terminal inside the build/ directory, execute: dc_shell -f ../scripts/run_synth.tcl | tee synthesis.log Use code with caution. 5. Troubleshooting Common Design Violations The generated gate-level output files are exported for
Are you encountering specific in your design?
. It uses physical information from the floorplan to provide more accurate timing estimates, reducing the "correlation gap" between synthesis and physical placement. Looking for more VLSI tools? Missing else or default statements in combinatorial always
Used to resolve cell references. The asterisk ( * ) tells DC to search its internal memory first before looking through external disk files.
